[R] Zeitreihen problem

[Wojtek Musial]

Thanks for the answer(s), but my specific problem is to change the objects
like

> disc[1,1]
 [1] 01/03/1955
 17647 Levels: 01/01/1956 01/01/1957 01/01/1958 01/01/1959 ... 12/31/2002

which are factors to a string like "01/03/1955". I can't find any way to
convert it to such a string, which can then be converted using for example

> strptime(datevec, format="%m/%d/%Y")

Anyone an idea?
